Torque is the measurement of a turning and twisting force. As an example, it is the force necessary to turn the head of a screw or bolt on all types of assembly applications ranging from small items like cell phones to an automotive chassis and more.Torx screws are typically used in vehicles, motorcycles, bicycles, computer systems, hard disk drives and consumer electronics. The unusual star-shaped head makes them far more secure than regular flat-head or cross-head screws and allows higher torque transmission so screws and bolts can be tightened more securely.
